9 Claims.

Our invention relates to a new and useful irnprovement in a vaginal syringe, and has for its object the provision of a syringe of this type which will be economical and highly eflicient in use, durable, easily and quickly operated, and possessed of features productive of the maximum oi comfort when in use.

Another object of the invention is the provision of a vaginal syringe whereby the flushing liquid may be delivered through the delivery conduit and at the same time carried away through the outlet conduit.

Another object of the invention is the provision of a syringe of this type in which the fluid delivered through the delivery conduit may be maintained until a pre-determined pressure is reached, whereupon it may be permitted to escape through the outlet conduit.

Another object of the invention is the provision in a syringe of this type of a longitudinally movable delivery pipe o'r nozzle which may be adjusted to various lengths.

Another object of the invention is the provision of a syringe of this type having a telescoping delivery pipe or nozzle so that it may be collapsed, and thus a device provided which will occupy a minimum amount of space when stored away.

Another object of the invention is the provision of a syringe of this type having simple and effective means for maintaining the outlet pipe or nozzle surrounded by a quantity of sterilizing medium when not in use.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood by referring to the accompanying drawing which forms a part of this specification, and in which,

Fig. 1 is a central sectional view of the invention.

Fig. 2 is a sectional view taken on line 2--2 of Fig. 1.

Fig. 3 is a fragmentary sectional View of another form of the invention.

Fig. 4 is a fragmentary sectional view of the form shown in Fig. 3 with the bulb collapsed.

Fig. 5 is a central sectional view of another vform of the invention, with the delivery pipe or nozzle in outwardly extended position.

Fig. 6 is a fragmentary sectional view of the form shown in Fig. 5 with the nozzle collapsed. In the form shown in Fig. 1, we have provided a collapsible bulb I2, formed from rubber or the (Cl. 12S- 232) like, and extended centrally through which is a rigid tube I3. end of the tube I3, so as to extend exterior of the bulb I2, is a nipple I4, on to which is threaded the delivery pipe or nozzle I5. The interior of the nipple I4 is in communication with the interior of the bulb I2 through the passages I6. Passages Il extending through the head I8 communicate with the interior of the tube I3.

The construction is such that when the bulb I2 is filled with liquid, and the delivery pipe I5 placed in position for use, a squeezing of the bulb will eject the liquid outwardly through the passage I6, and through the delivery pipe or nozzle I5.

The face I9 of the bulb will engage against the body sufficiently to effect a sealing connection, and the liquid delivered through the nozzle or delivery pipe I5, after flushing, will flow through the passages I'I, and outwardly through the outlet pipe I3. Thus there is provided a simple and effective means for maintaining a constant flow of ilushing liquid by the use of a syringe of this type.

In Fig. 3, we have shown a bulb I2, with a tube I3 extended centrally therethrough, and provided at one end with the head I3. This tube I3 is formed from hard rubber or the like, sufficiently stable to retain its shape. The head I8', however, is formed from flexible rubber and imbedded at one end in the head I8 are the rigid arms 29 having the curved ends 22 and extended angularly to the tube I3', which forms the axis of the bulb I2. Inwardly of one end of lthe head I8', and projecting outwardly therefrom, is the delivery tube or nozzle 23, communicating through passage 24, with the interior of the bulb I2. The face I9 of the bulb will be pressed against the body to effect a sealing connection. When the bulb I2 is squeezed, the liquid therein will beexpelled through the passages 24 outwardly through the delivery pipe 23. As the liquid is delivered through the delivery pipe 23 and the face I9 held in sealing connection against the body, it is obvious that a pressure will be built up in the vagina. This will continue until the bulb I2 is pressed inwardly sufficiently to engage the arms 20, and rock them inwardly on the point 23', which is formed from the nozzle-or pipe 23 may pass into the outlet` Projecting outwardly from one.

pipe or tube i3. In this way, we have provided a syringe whereby a constant now, inwardly and outwardly, oi the liquid will take place after a pre-determined amount of liquid has been delivered. Thus there is afforded a means for building up a pressure before the escape of liquid takes place.

The position of the various parts in the escaping position is clearly shown in Fig. 4.

In Fig. 5 and Fig. 6, we have shown a bulb provided at one end, projecting outwardly from the face lg', with a tapered neck 28, which when in use, is adapted to extend between the vulva. Projecting through the bulb and extending outwardly or" the neck 28, is an outlet tube 29. This tube 2S is formed of hard material and is provided, at the end which projects through the wall 30 of the bulb, with a flexible portion 3l, in which are imbedded the ends of the arms 28' having the curved ends 22. Surrounding the outlet tube 2Q is a ring 32 of a hard material, which serves as a fulcrum for the arms 2li. Projecting inwardly from the exible portion is` a bead 33. Slidably mounted in the tube 29 is the nozzle or outlet delivery pipe 34, which is formed from hard rubber or the like. In the periphery of this tube Sdi are formed grooves 35. The discharge opening 36 in the outlet pipe or nozzle 3l! is threaded to receive the threaded stud of the cup shaped cap 3B, which is provided on the base with the peripheral iiange 39. Resting on the inner surface 'of the base of the cap is a washer or gasket 4G. The nozzle or outlet pipe Sli may be telescoped within the tube 29, as shown in Fig. 6, and when in this position the cap 38 may be secured on the nozzle 34 by means of the threaded stud 3i', so that the gasket 5U will bear against the end of the nozzle or pipe 34. The cup will also engage the face I9 in sealing connection. When in this position, the stud 3l will be threaded into the threaded end of the small delivery tube fil. This tube 4| extends centrally of the tube 39, and is` formed with the T-branches a2 at its inner end, which projects through the tube 29, and form a means for communicating the interior of the outlet pipe o1' nozzle 35i with the interior of the bulb 2l'. This tube i slidably projects through the cap 43 which serves as a closure for the rear end of the nozzle or delivery pipe 34. The rear end of this delivery pipe is provided with grooves 44 formed on its periphery. When in the collapsed position shown in Fig. 6, the tube 29 may be filled with suitable sterilizing material, and this sterilizing material will be in contact with the entire surface of the pipe 34. When the tube 29 is lled with the sterilizing material, a plug may be threaded into threaded portion 625 of the tube 29, and serve to close this tube.

When it is desired to use the device, the cap 38 may be threaded outwardly until the stud 31 disengag'es from the tube 4|, whereupon by gripping the iiange 39, the entire structure may be pulled outwardly and the cap then removed from the delivery pipe or nozzle 34. In this act or movement, the iiexible end 3l of the tube 2S will engage in the grooves 35, or the nozzle may be pulled outwardly so that the bead 33 engages in these grooves. When the bulb 21 is lled with cleansing liquid, a squeezing of the bulb will force the liquid through the T-branches A2, and through the tube 4l, into the delivery pipe or nozzle 311. The face I9' of the Wall 30, will be of course held against the body in sealed connection so that a pressure will be built up until the arms 29 are rocked inwardly at their free ends to raise the fiexible portion outwardly from the periphery of the nozzle 34, and permit the liquid to escape, by means of the grooves 4M, into the interior of the outlet tube 2S. It is believed obvious that, if desired, a suitable outlet delivery pipe may be connected to the threaded portion 55, for conducting the escaping fluid to any desired location or receptacle.

The advantages obtained from the use of the device shown in Fig. 1, and Fig. 3, are present in the structure illustrated in Fig. 5, and Fig. 6. But in the structure illustrated in Fig. 5 and Fig. 6, the delivery pipe or nozzle will be telescoped so that the device may be collapsed into very compact form, thus affording a device which will occupy a minimum amount of space when stored away.

The facility of maintaining the nozzle surrounded by a sterilizing medium when not in use, which is present in the form shown in Fig. 5, is of course not present in the other forms as shown.

The tubes i3, i3 and 2S, are secured to the bulb preferably by being vulcanized thereto.

It is thus seen that we have provided a syringe of this kind which is capable of functioning to a maximum degree of eiiiciency while at the same time the operation of the device is very simple and easily effected.
